3. Tia Mowry

Mowry chopped her hair into a pixie in October, a look inspired by her son, Cree. “amp#91;The birth ofamp#93; my son has given me a whole new perspective and outlook on life," she told InStyle.com "I’m not the same person I was before. Hair comes with a lot of experiences and emotions: It’s out with the old and in with the new.” We agree!

4. Rihanna

Despite her fun, spontaneous nature, Rihanna's pixie crop wasn't a spur-of-the-moment decision. "We’ve been talking about going short for a little while now, and we actually planned to cut it the following week," said the star's hairstylist Ursula Stephen. "I just felt like-why wait... Rihanna was ready for her short hair again."See Rihanna's edgy hairstyles-on you.

5. Julianne Hough

Hough chopped her long layers into a chin-skimming bob in June, but she's tempted to make even more hair changes. "I keep going shorter, it's like the curse of the short hair syndrome," Hough told InStyle. "My friend has a pixie cut, and I've been wanting to do her style. I probably won't do that, but I want to!"

6. Charlize Theron

Theron made quite a buzz when she went for a completely-shorn hairstyle in June. The change was for her role as Furiosa in the post-apocalyptic film Mad Max: Fury Road. "Charlize takes her trade very seriously. She’s not afraid to put herself out there and transform into the character she’s playing," said Theron's stylist Leslie Fremar. "And let's be honest, she's so beautiful!"
